Check BackupEdge at htt://
I am venturing into linux myself but have used this product for backup for year, it is great. I've used it on the SCO UNIX platform.
With its recovery disks (you create them), you can restore from tape, dvd/cd and have a full restore in a couple of hours (depending on size). If your media is bootable media, you have the option to create bootable backup, bit by bit comparision, email notification, prints results to printer, etc, etc, ...
As far as I am concerned, this backup program is second to none. Their support is great, very friendly staff.
Check them out, I am sure you'll find them to be worth your time.
Good luck!
